Abstract

La presente invención se refiere a anticuerpos dirigidos contra HLA-G y formulaciones que los comprenden. La invención se refiere, además, al uso de los anticuerpos HLA-G y formulaciones en tratamientos, en especial en el tratamiento de tumores sólidos. Reivindicación 1: Un anticuerpo que se une específicamente a HLA-G, en donde el anticuerpo comprende: a. una región variable de cadena ligera que comprende: i. una CDR-L1 que comprende el SEQ ID Nº 1; ii. una CDR-L2 que comprende el SEQ ID Nº 2 y iii. una CDR-L3 que comprende el SEQ ID Nº 3, y b. una región variable de cadena pesada que comprende: i. una CDR-H1 que comprende el SEQ ID Nº 4; ii. una CDR-H2 que comprende el SEQ ID Nº 5 y iii. una CDR-H3 que comprende el SEQ ID Nº 6. Reivindicación 22: Un anticuerpo que compite de forma cruzada con el anticuerpo de la reivindicación 1 para unirse a HLA-G o se une a un epítopo de HLA-G que comprende V194, F195, Y197, E198, Q224, Q226, D227, V248, V249, P250 e Y257 de HLA-G (SEQ ID Nº 107). Reivindicación 23: Un polinucleótido aislado que codifica el anticuerpo de acuerdo con una cualquiera de las reivindicaciones 1 a 22. Reivindicación 26: Un vector de clonación o de expresión que comprende uno o más polinucleótidos de acuerdo con una cualquiera de las reivindicaciones 23 a 25. Reivindicación 27: Una célula hospedante que comprende uno o más polinucleótidos de acuerdo con una cualquiera de las reivindicaciones 23 a 25 o uno o más vectores de expresión de acuerdo con la reivindicación 26. Reivindicación 28: Una célula hospedante que comprende uno o más polinucleótidos de acuerdo con una cualquiera de las reivindicaciones 23 a 25 o uno o más vectores de expresión de acuerdo con la reivindicación 26, en donde la célula hospedante fue modificada genéticamente para disminuir o suprimir la función de la a1,6 fucosiltransferasa. Reivindicación 29: Un proceso para la producción de un anticuerpo de acuerdo con una cualquiera de las reivindicaciones 1 a 22, que comprende cultivar la célula hospedante de acuerdo con la reivindicación 27 o 28 en condiciones adecuadas para producir el anticuerpo y aislar el anticuerpo. Reivindicación 30: Un proceso para la producción de una composición farmacéutica que comprende el anticuerpo de acuerdo con una cualquiera de las reivindicaciones 1 a 22, que comprende las etapas del proceso como se define en la reivindicación 29 y que comprende, además, formular el anticuerpo en una composición farmacéutica. Reivindicación 31: Una composición farmacéutica que comprende el anticuerpo de acuerdo con una cualquiera de las reivindicaciones 1 a 22 y uno o más vehículos, excipientes o diluyentes farmacéuticamente aceptables.
